WILLIAM C. HOMAN, OF MERIDEN, CONNECTICUT.

ACETYLEINE-GAS GENERATOR.

$PEGIFICATION formingpart of Letters Patent No. 713,640, dated November18, 1902- Application filed February 19, 1902. Serial No. 94,739. (Nomodel.)

T0 (11 111710112, it may concern:

Be it known that I, \VILLIAM C. HOMAN, a citizen of the United States,residing at Meriden, county of New Haven, State of Connecticut, haveinvented certain new and useful Improvements in Acetylene-Generators, ofwhich the following is a full, clear, and exact description.

My invention relates to acetylene-generaators, and in the drawingsI haveshown a generator in the form of a lamp which provides an automaticfeeding mechanism whereby the proper quantity of carbid is intermittently fed to a water-chamber, whereupon the gas is generated andfed to the burner.

My invention relates particularly to the construction of the generator,whereby the parts are simplified and the necessity of having more thanone opening into the generating chamber is avoided. In this sense I meanto include the carbid-chamber and the water-chamber as constituting thegas-generating chamber. Manifestly it is necessary to get access to boththe water and carbid chambers in order to fill or clean them. This isaccomplished in a novel and effective manner.

The improvement herein also permits me to get a more ready access to theinterior of the carbid-chamber and to the valve.

In the drawings, Figure l is a side elevation, mainly in section, of agenerator in the form of alamp, the bottom of the liquid-chamber beingbroken away. Fig. 2 is a similar view of the lamp inverted, a portion ofthe mechanism shown in Fig. 1 being removed from the lamp for thepurpose hereinafter described. Fig. 3 is a side elevation, partly insection, of the detached portion. Fig. 4 is a vertical sectional view ofa lamp embodying my invention, showing an operating mechanism therefor.

A is a casing forming a chamber in which the carbid is placed.

B is a receptacle for water. 7

The casing A is connected to the receptacle B by means of a joint ofapproved pattern which preferably includes a packing-ring D, which whenthe parts are coupled together hermetically seals the joint, preventingthe escape of any of the contents of the generator.

The carbid-receptacle A is spaced apart from the receptacle 13 by what Ishall term a tubular shank E of symmetrical proportions and ofsufficient size to afford accommodation for the valve and adjacentparts.

G is a valve-seat, preferably made of suitable material, such as rubber,which can coact efiectively with the valves F F, so that when either ofthe valves is in engagement with said seat it will properly close thepassage between the carbid-receptable A and the water-receptacle B.

A convenient manner in which the valves F and F may be operated will behereinafter described.

It is apparent from an inspection of the drawings that there is no wayfor affording access to the interior of the carbid-receptacle unless thegenerator is taken apart. Heretofore it has been common to provide asuitable port or opening fitted with a screw-cap affording a means forfilling the carbid-chamber from the outside. This, it is believed, isundesirable, since in the event the cap is not screwed into place verytightly leakage might occur. removable stopper of very much largerproportions than could be provided by means heretofore employed, whichstopper cannot be removed until the generatoris taken down, and whichstopper must necessarily be secured properly in place before thegenerator can be used at all.

In the drawings it will be observed that within the shank E there is aseparate member H, corresponding generally in shape to the interior ofthe shank E. The upper part of this member H affords a housing orsupport for the valve-seat G, which may be secured thereto convenientlyby an annular cap G.

I is a packing of suitable material located between the exterior of themember H and the interior wall of the shank E. When the parts are in theposition shown in Fig. 1, this packing I is under the desiredcompression to effectively seal the passage aside from the sealing ofthe valve within the seat G. As particularly shown, there is a shoulderE, provided Within the shank E, against which the To that end,therefore, I provide a packing I impinges. Manifestly this shoulder maybe provided in a variety of ways obvious to the mechanic skilled in theart.

Within the lower part of the shank E is provided an inclined ledge J,and by preference a pair of these ledges is provided for the purposehereinafter described.

K K are studs provided on opposite sides of the member H, and thesestuds are adapted to coact with the inclined ledges J, so that themember H may be connected with the shank E bya joint similar in effectto the bayonet-joint. To that end the notch J is provided adjacent toeach ledge J, so that the studs K can be introduced properly. Manifestlya screw-joint might be used; but this effect generally is shown as aconvenient method of attaching said member H to the shank E. Tofacilitate detachment, the studs K may project inward slightly, and aspring yoke or handle K maybe provided with each generator outfit, whichhandle may be engaged with the inside of the studs K, so that theoperator may easily unseat and remove the member H. The member H, Ishall term herein and in the following claims a stopper, in that itsfunction is to stop the passage leading into the carbid-receptacle fromthe liquid-receptacle, and vice versa, except, as before stated, to theextent that that passage is stopped by the valve F or F.

L and L are catches adapted toattach the shank to the base by coactingwith the lugs M and M, respectively.

To fill the generator, the upper part is detached from theliquid-receptacle B and then inverted and caused to assume the positionshown in Fig. 2, in which, it will be observed, the shade-support N maybe used as a standard. The handle K is then connected with the studs K Kand the stopperH is removed, thus affording a free access to theinterior of the carbid-chamber, and also affording a generous spacethrough which to insert such cleaningimplements as may be desired ornecessary in order to properly clean said chamber or the valves F F.

O is a plate which is preferably located in the top of thecarbid-chamber and which when the generator is in the position shown inFig. 2 serves as a bottom upon which the carbid may be deposited beforeinserting the stopper H and inverting the position of the parts. Thisplate 0 serves to prevent any loose carbid from getting up into the topof the generator, where it might possibly clog some portion of thecontrolling mechanism. When the proper amount of carbid has beeninserted into the receptacle A, the stopper H is inserted and secured,the handle K is removed, the liquid-receptacle B is filled with thedesired amount of water, and the parts are assembled in the positionshown in Fig. 1. The line of connection occurring at the packing Dbetween the carbid and the liquid-receptacle is the onlypoint at whichaccess may be had to the interior of the lamp.

The generation. of gas may be controlled by a suitable mechanism-as, forexample, that shown in Fig. 4C. The valves F and F may be carried by avalve-rod, which passes up through a tube P and is attached to the topof a collapsible gas-reservoir R. The pressure of the gas which iscontained in the receptacle A is then communicated to the reservoir Rand causes the valves to rise and fall as it passes outward to theburner. When the lamp is in its inoperative position, the valve F closesthe passage between the carbid and water receptacles. To set the lamp inoperation, the operating-stem T may be moved so as to raise thevalve-rod by means of the lever S. This lever S is pivoted at s andsuitably connected to the top of the collapsible gas-reservoir. Theraising of the valve-rod and the valves permits the carbid in thereceptacle A to fall intermittently into the water-receptacle. Gas isthen generated and passes up through the collapsible gasreservoir, whichby its operation automatically opens and closes the valves F and F.

What I claim is 1. In an acetylene-generator, a carbid-receptacle, adetachable liquid-receptacle, and a removable stopper for the formerlocated between said liquid-receptacle and said carbid-receptacle andcarrying a valve-seat.

2. In an acetylene-generator, a carbid-receptacle, and aliquid-receptacle access being had to said carbid-receptacle only bymeans of a connection between said carbid-receptacle and saidliquid-receptacle and a removable stopper for closing theaccess-passage.

In an acetylene-generator, a carbid-receptacle, a detachableliquid-receptacle, a valve between the same, and a removable stopperlocated between said liquid-receptacle and said carbid-receptacle, and avalveseat carried bysaid stopper said stopper closing the space betweensaid valve and said carbid-receptacle.

4:. In an acetylene generator, separate chambers for the gas-generatingelements, a passage from one to the other, a valve therefor, avalve-seat for said valve, means for attaching said two chamberstogether, a removable stopper and a packing-ring for said stopper.

5. In an acetylene-generator, a carbid-receptacle, a water-receptacle, apassage from one to the other, a valve for said passage, a valve-seatfor said valve said valve-seat being carried by a stopper removablethrough said passage.

6.
